So I was up late last night working on a test campaign to get it going. As usual Adwords Editor was taking its sweet time to upload the campaign, after I had finished the keywords and ads. It was fairly late around 1am and I was sleepy, for some reason I get more done late at night 
Well, I woke up this morning to find out I was over $700 in the hole! In my rush to finish I forgot to disable the search network as this was suppose to be a content only campaign. That little check box cost me a pretty penny. I hate to lose money, so any amount is not fun.
Yeah I could have had a lower budget, but content is usually slower to be approved so I figured by the time I wake up it would have just got going. Unlike search where it is usually pretty fast for me.
Moral of the story is don’t get sloppy when launching campaigns. I think I’m going to write up a pre-launch checklist just because of this as there are a handful of things that should be checked.
I hate when this happens. I have read about it on several blogs before, you forget one setting and you end up largely in the whole. There are so many settings you can forget with Adwords too because so many exist. It is just a good reminder you have to be really careful. But I think you have learned your lesson
